JavaZone report, day 1, half-done

Updated with hyperlinks

Was at Bruce Johnson's talk on Google WTK. Cool stuff, Google, nuff said. Will have to try it out.

Then on to Jevgeni Kabanov's talk on Arenea. Interesting ideas, but I don't really think this is anything ready for prod. I'm an OO guy, so I can really see the use of using more OO in webapps. Might try this out next year if it's still alive.

Took a one session break.

Now in Bruce Tate's Java/Ruby integration talk. So far doing very well being diplomatic towards java (perhaps very wisely). Alotta RoR demonstration, and the ReST stuff was of course impressive. Tate is by the way one helluva talker. Sounds a bit like an American president (scaringly smoothly convincing type), but I think he's Texan, after all :)

Now I've stumbled into Ross Mason's Mule/JavaSpaces . The nickle in his shoe is handling meta-data for web services. but ESBs, or was it WSDLs, don't provide this too well.

Now normally I like to stay clear of the service layer, but I don't think I can too much longer. Will remember stuff like ReST and JavaSpaces if I ever journey into such landscapes. Quite simply. Mule seems like a bus. This I will have to try soon as well. Too many beer-talks about remoting I want in on these days!

Had a quick discussion with Rickard Öberg earlier, trying to explain him the benefits of having a standardized content repository (JSR-170). Now from his point of view, most of the requirements (migration, search and even versioning) is handled by the transport/data layer format, RDF. Why standardize beneath that (other than making it more developer standard)? Now I just had a qiock look at the spec, and there's one use case I didn't think of during discussion, and that is events.

I also talk to Alex Popescu for a tiny bit, figured me and him could gang up on Rickard. Anyhows, Rickard was gonna show him a quick SiteVision demo, and I guess that would get him rolling (heard he can pick quite a verbal fight, according to the tales of speakers' night out yesterday). Looking forward to his talk about InfoQ.

Afterwards it's onto Bjørn's talk on some ORM performance stuff. Will try to update when the beer's out.

Open source CMS evaluations

I have now seen three more or less serious open source CMS reviews. First guy to hit the field was Matt Raible ( 1 2 3 4 ), ending up with Drupal , Joomla , Magnolia , OpenCms and MeshCMS being runner-ups. Then there is OpenAdvantage that tries out a handful ( Drupal , Exponent CMS , Lenya , Mambo , and Silva ), including Plone which they use for their own site (funny/annoying that the entire site has no RSS-feeds, nor is it possible to comment on the articles), following Matt's approach by exluding many CMS that seem not to fit the criteria. It is somewhat strange that OpenAdvantage cuts away Magnolia because it "Requires J2EE server; difficult to install and configure; more of a framework than CMS", and proceed to include Apache Lenya in the full evaluation. Magnolia does not require a J2EE server. It runs on Tomcat just like Lenya does (maybe it's an idea to bundle Magnolia with Jetty to make it seem more lightweight). I'm still sure that OpenAdvant

Encrypting and Decrypting with Spring

I was recently working with protecting some sensitive data in a typical Java application with a database underneath. We convert the data on its way out of the application using Spring Security Crypto Utilities . It "was decided" that we'd be doing AES with a key-length of 256 , and this just happens to be the kind of encryption Spring crypto does out of the box. Sweet! The big aber is that whatever JRE is running the application has to be patched with Oracle's JCE  in order to do 256 bits. It's a fascinating story , the short version being that U.S. companies are restricted from exporting various encryption algorithms to certain countries, and some countries are restricted from importing them. Once I had patched my JRE with the JCE, I found it fascinating how straight forward it was to encrypt and decrypt using the Spring Encryptors. So just for fun at the weekend, I threw together a little desktop app that will encrypt and decrypt stuff for the given password

What I've Learned After a Month of Podcasting

So, it's been about a month since I launched   GitMinutes , and wow, it's been a fun ride. I have gotten a lot of feedback, and a lot more downloads/listeners than I had expected! Judging the numbers is hard, but a generous estimate is that somewhere around 2000-3000 have listened to the podcast, and about 500-1000 regularly download. Considering that only a percentage of my target audience actively listen to podcasts, these are some pretty good numbers. I've heard that 10% of the general population in the western world regularly listen to podcasts (probably a bit higher percentage among Git users), so I like to think I've reached a big chunk of the Git pros out there. GitMinutes has gathered 110 followers on Twitter, and 63, erm.. circlers on Google+, and it has received 117 +'es! And it's been flattr'ed twice :) Here are some of the things I learned during this last month: Conceptually.. Starting my own sandbox podcast for trying out everythin

The academical approach

Oops, seems I to published this post prematurely by hitting some Blogger keyboard shortcut. I've been sitting for some minutes trying to figure out how to approach the JavaZone talk mentioned in my previous blog-post. Note that I have already submitted an abstract to the comittee, and that I won't publish the abstract here in the blog. Now of course the abstract is pretty detailed on what the talk is going to be about, but I've still got some elbow room on how to "implement" the talk. I will use this blog as a tool to get my aim right on how to present the talk, what examples to include, what the slides should look like, and how to make it most straightforward and understandable for the audience. Now in lack of having done any presentations at a larger conference before, I'm gonna dig into what I learned at the University, which wasn't very much, but they did teach me how to write a research paper, a skill which I will adapt into creating my talk: The one

Managing dot-files with vcsh and myrepos

Say I want to get my dot-files out on a new computer. Here's what I do: # install vcsh & myrepos via apt/brew/etc vcsh clone https://github.com/tfnico/config-mr.git mr mr update Done! All dot-files are ready to use and in place. No deploy command, no linking up symlinks to the files . No checking/out in my entire home directory as a Git repository. Yet, all my dot-files are neatly kept in fine-grained repositories, and any changes I make are immediately ready to be committed: config-atom.git     -> ~/.atom/* config-mr.git     -> ~/.mrconfig     -> ~/.config/mr/* config-tmuxinator.git       -> ~/.tmuxinator/* config-vim.git     -> ~/.vimrc     -> ~/.vim/* config-bin.git        -> ~/bin/* config-git.git               -> ~/.gitconfig config-tmux.git       -> ~/.tmux.conf     config-zsh.git     -> ~/.zshrc How can this be? The key here is to use vcsh to keep track of your dot-files, and its partner myrepos/mr for o
